yeah its an age old guerilla tactic. Strategy of tension.
It is, but it is questionable whether these attacks were carried out with that degree of thinking. Loads of terror groups had the capability to do this sort of massacre-thing down the years (including the Kouachi brothers), but they didn't because they knew what the scale of the state's response would be, and that no-one (or at least a vanishingly small number of people) would oppose it, and the incentive to dob those involved in planning these things would be very real and very compelling (and very correct).
